Android updates released as OTA packages are very easy to apply, but they also cause major headaches to custom ROM lovers. Every time an OTA comes out, we need to revert back to stock recovery, flash the update, and then flash our favorite custom recovery like TWRP or ClockworkMod to get back all of our recovery features like Nandroid backups and the ability to flash SuperSU. I don’t even have to begin to cover how time consuming and frustrating this process is.
If your device gets these updates frequently, you might be interested in testing a tool created by XDA Forum Moderator and Recognized Developer graffixnyc. Simple Recovery Switcher, as the name states, easily switches between stock and custom recovery. The whole process can be done pretty much in no time, which is much faster than using a standard USB cable with the fastboot method.
The application should work as intended on every Qualcomm device that uses the /dev/block/platform/msm_sdcc.1/by-name/recovery structure and is rooted with Busybox installed. Recoveries must be named stock.img and custom.img and must be placed in the root folder of your internal SD Card. Before using this tool, double check everything, since messing with recoveries may result in a bricked device.
Android L or Lemon Meringue Pie is on its way, so there might be some OTA updates available in the near (or not so near) future. Prepare yourself for OTAs by visiting the Simple Recovery Switcher application thread._________
